Antilock Brake System ABS
ABS prevents locking of the wheels during brak-
ing. Safe steering response is maintained even
during full braking. Active safety is thus
increased.
Braking safely, refer to page93.
Among others, ABS includes the following func-
tions:
>Cornering Brake Control CBC
>Electronic brake-force distribution EBV
>Brake Assist
Cornering Brake Control CBC
Driving stability and steering characteristics are
further enhanced while braking in turns or dur-
ing a lane change.
Electronic brake-force distribution EBV
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
Brake Assist
Rapidly depressing the brake causes this system
to automatically develop maximum braking
force. Thus, the system helps keep braking dis-
tance to a minimum. At the same time, all the
benefits provided by ABS are exploited.
Do not reduce the pressure on the brake for the
duration of the full braking application.
Dynamic Stability Control DSC
DSC prevents the driving wheels from losing
traction when you pull away from rest or accel-
erate. The system also recognizes unstable driv-
ing conditions, for example if the rear of the car
is about to swerve or if momentum is acting at
an angle past the front wheels. In these cases,
DSC helps the vehicle maintain a safe course
within physical limits by reducing engine output
and through braking actions at the individual
wheels.
DSC also encompasses the following functions:
>Antilock Brake System ABS
>Electronic brake-force distribution EBV
>Brake Assist>Cornering Brake Control CBC
>Hill Assist
Deactivating DSC
Press the button repeatedly until the DSC indica-
tor lamps come on. DSC is deactivated. Stabiliz-
ing and propulsion promoting actions are no
longer executed.
When driving with snow chains or to 'rock free'
in snow, it can be helpful to switch off DSC for a
brief period.
To increase vehicle stability, activate DSC again
as soon as possible.
Activating DSC
Press the button again: the DSC indicator lamps
go out.
For better control
If the indicator lamp flashes:
The DSC controls the driving and break-
ing forces.
If the indicator lamps are on:
DSC is deactivated.
Dynamic Traction Control DTC*
DTC is a type of DSC that is propulsion optimized
for special road conditions such as uncleared
snowy roads. The system ensures maximum
propulsion though with restricted driving stabil-
ity. You therefore need to drive with suitable
caution.
In the following exceptional situations, it can be
useful to briefly activate DTC:
